Problem adding tattoos

I needed to add a simple tattoo to this guy's back (m4) -

Tried to use 3d paint but I'm getting this weird dotted line down the midline going up on to the head

When I limited the area for painting (excluded head) had similar midline problem, just limited to torso

Any idea what's causing this or how to fix in C8.5 pro?

(This render was with photorealistic setting, but I'm going to be using Digital Carver Guild's toon pro and going for a noir look, so instead of using texture map just have a shade of white/gray in the color channel) - otherwise would have just done tattoo in photoshop.

(do have layered image editor - don't know if that's of any value in carrara or daz only)

(and this will be animated so can't just apply in post)
Thanks

    That would be the back seam line. When making textures always add some "seam allowance" aka "buffer" zone.

    Not sure I understand how to fix that in this case or if that problem would apply here.
    Again, for example, if I want to use 3d paint to make a texture of the torso of m4 which will basically be light gray with some black squiggles for tattoos, how would I do that? (how would I add the buffer space you're talking about)

    Thanks

    He's talking about on a texture map - it's good to paint a bit outside the line, so you don't get white on the mesh.

    Try turning off Symmetry, and see if the issue is eliminated. If that works, just use PS to copy and flip what you paint to make it symmetrical on the other side.

    Also, you could use an M4 texture map as a template in PhotoShop. Paint the tattoo you want, eliminate the original image, retaining the size and position, and select everything except the tattoo as Alpha and save as a png (or tga, tiff, etc.,) with alpha, and "multiply" that png against the existing color channel. Instead of Multiply, you could try any of the other operators as well, like Add, Subtract, divide, etc., experiment a bit. The alpha in the png will isolate you're new source in the color channel to only show your tattoo painting.

    My copy of 3D paint is an older version ... think it still works about the same though. You load the .obj file and apply a large blank .png file to it. Then paint on it. Zoom in close for the seam areas.
    Export out the .png file to wherever you please.
    Bring it into your 2D image editor which works with layers, and a texture template [on product page or in your account's product library or from other websites or created via a modeler or a utility such as UVViewer] ... layer them so you can see how well 3D paint worked and where to add a little more for the seam allowance. Hide the template layer and save out the .png file to test results ... takes some time and effort to get the best match which makes for a good reason not to put too much detail right over the seams ;-)

    To add a buffer zone ... in the 2D image editor, paint outside the template lines.

    dartanbeck and patience -

    Appreciate your help. I'm working through a bunch of scenes for a project and will try some of the suggestions you gave when I get back to the tattoo scene.

    Patience is a virtue
